Embodiment approach 1
[0034] Adopt the liquid magnetic grinding tool of the present invention, to the diameter 30mm magnetic material 45 steel specimens and non-magnetic material duralumin (YL12) specimens were tested respectively, 45# steel and hard aluminum alloy YL12 two Nine pieces of each material were divided into two groups and tested in an orthogonal manner. The liquid magnetic grinding tool that experiment adopts is by water 195 grams (weight ratio 31.4%), carbonyl iron 270 grams (weight ratio 43.4%), sodium dodecylsulfonate 6.2 grams (weight ratio 1%) and 54 purpose silicon carbide abrasives 150 grams (24.2% by weight) for preparation; sodium dodecyl sulfonate was added to water, and mechanically stirred for 10 minutes to disperse it evenly in the base liquid; carbonyl iron particles were added to the base liquid and the surface In the mixed solution of the active agent, and use a stirrer to fully mix, the mixing time is 4 hours; add the silicon carbide abrasive to the mixed solution of t...

[0044] Adopt the liquid magnetic grinding tool of the present invention, to the diameter 30mm magnetic material 45 steel specimens and non-magnetic material duralumin (YL12) specimens were tested respectively, 45# steel and hard aluminum alloy YL12 two Nine pieces of each material were divided into two groups and tested in an orthogonal manner. The liquid magnetic abrasive tool that experiment adopts is made of water 200 grams (weight ratio 29.96%), carbonyl iron 280 grams (weight ratio 41.95%), sodium dodecylsulfonate 7.5 grams (weight ratio 1.12%) and 80 mesh silicon carbide abrasives 180 grams (weight ratio 26.97%) preparation. Add sodium dodecylsulfonate into water, and use mechanical stirring method to stir for 30 minutes to disperse it evenly in the base liquid; add carbonyl iron particles to the mixed solution of base liquid and surfactant, and use stirring The mixing time is 6 hours; the silicon carbide abrasive is added to the mixture of base liquid, surfactant and p...
